Luck came back to town Saturday to help launch "Change the Play," a campaign intended to keep children active and make good nutritional choices. He's working through Riley Hospital for Children.

The Colts quarterback and his teammates are scheduled to begin their offseason workout program at the team complex this week, and it's the first time Luck will work extensively with new offensive coordinator Pep Hamilton, who replaces Bruce Arians. The good news for Luck is that he won't be starting from scratch.

Hamilton and Luck worked together when the two were at Stanford, though Hamilton is tweaking the system for the NFL.
